Abstract (en)
[origin: WO2022153710A1] To provide an efficient and stable training process even in a case where a small amount of target domain labeled data is available. Solution to Problem A training apparatus (1)comprises: feature extraction means (11) for extracting source domain feature values from source domain data and for extracting target domain feature values from target domain data; prediction means (12) for predicting source domain class prediction values from the source domain feature values and for predicting target domain class prediction values from the target domain feature values; filtering means (13) for computing filtered source domain feature values and filtered target domain feature values by filtering out one or more values from the source domain feature values with reference to the source domain class prediction values and by filtering out one or more values from the target domain feature values with reference to the target domain class prediction values; and updating means (14) for updating at least one of the feature extraction means and the class prediction means.
